ML3120/ML3121 series supports LTE-FDD and LTE-TDD, alone with DC-HSPA+ in a Mini PCle package. With 3GPP Rel.9 and LTE Cat4, which provides data transfer up to 150kbps for downlink and 50kbps for uplink. ML3120/ML3121 supports DC-HSPA+ guaranteed connectivity even in areas that do not yet have LTE coverage where backwards compatibility with 3G and 2G newwork is desired. Typical applications are wireless payment,smart home,security monitoring, and industrial router etc.
